My brother and husband tried for days, to install all this equipment, we received as a gift. We went to Best Buy, but those guys were clueless. We then tried calling around and nobody seemed like they wanted to help us. So, a friend of my husband recommended we go to Sound Solutions. Apparently they've been in Chantilly forever and a day and had done some work for him, in the past.
Long story short, we took the vehicle in to them and the guy spoke with intelligence and complete confidence. They were able to install everything and put the car back together in less than a day! It didn't look to me, like the car would ever go back to normal! I was scared to death. PLUS, they were able to make my check engine light go away.
These people really know what they're doing and will take good care of your vehicle.
